Destructive Fibrosarcoma of the Maxillary Sinus.

Paranasal fibrosarcoma of nasal cavity and paranasal sinuses is a very rare malignant tumor. It is usually presented with nasal obstruction and epistaxis. In this clinical report, clinical symptoms, pathogenesis, and treatment principles of a paranasal fibrosarcoma originating from the right maxillary sinus and obstructing the right nasal passage are discussed.A 55-year-old male patient was admitted to the authors clinic with complaints of nasal obstruction and epistaxis lasting for 2 years. Anterior rhinoscopy revealed a mass lesion which obstructed the right nasal passage and caused frequent epistaxis. An opacity consistent with soft tissue lesion which was originated from the right maxillary sinus and filled the right nasal passage was observed in paranasal tomography. Magnetic resonance imaging revealed that the mass lesion was contrasted. Tumor was seen to erode orbital floor, and lateral and anterior walls of the maxillary sinus. Biopsy result was reported as papilloma. The patient was treated with Denker approach as anterior wall of the maxillary sinus was eroded by the tumor lesion and the mass lesion was excised. The patient received postoperative radiotherapy as pathological diagnosis was reported as paranasal fibrosarcoma.

Evaluation of auditory and cochlear functions in ankylosing spondylitis patients according to the site of involvement.

Ankylosing spondylitis (AS) is a chronic systemic inflammatory disease of unknown origin with a prevalence rate about 1% in the population. Audiovestibular dysfunction is encountered in AS and sensorineural hearing loss is the most common form. The present study aimed to evaluate auditory and cochlear function in AS patients according to the site of involvement. A total of 47 patients followed for AS in the rheumatology outpatient clinic and 30 healthy controls were enrolled in the study. Subgroups of AS were identified according to the site of involvement. The participants underwent complete otolaryngological examination together with audiometry, otoacoustic emission and tympanometry tests. Disease Activity Index (BASDAI) was determined in the AS group. Hearing loss was detected in seven patients (15%) in the AS group and in four subjects (8%) in the control group. There was statistically significant difference between the patient and control groups in terms of mean bone conduction hearing level at 4000 hertz (Hz) in the right and left ears (p = 0.028, p = 0.049). There was no significant difference between the subgroups of AS in terms of overall auditory and cochlear functions. No correlation was determined between auditory values and Disease Activity Index and CRP (p > 0.05 for all). Our results reveal that AS has minimal effect on auditory and cochlear functions. The effects of subgroups of AS on auditory functions were comparable. The authors concluded that BASDAI and CRP are not convenient in monitoring auditory functions of AS patients.

The effects of septoplasty surgery on serum oxidative stress levels.

The aim of this study is to compare the total antioxidant status (TAS), total oxidant status (TOS), and paraoxonase (PON1) serum levels in patients who have undergone septoplasty (NSD). Forty-six patients (mean age 33.7) aged between 18 and 50 years who were diagnosed with nasal septal deviation (NSD) were included in the study. The TAS, TOS, and PON1 levels were compared in the serum samples obtained 1 month before the septoplasty and 3 months after surgery. There was a significant increase in mean TAS after septoplasty (1.041 vs. 1.124 mmol/L, p = 0.011). The mean TOS decreased significantly after septoplasty (20.631 vs. 5.946 mmol/L, p = 0.011). The mean pre- and postoperative PON1 levels were similar (326.93 ± 215.22 vs. 275.20 ± 167.76 U/L, p = 0.253). Increased TAS and decreased TOS after septoplasty show that patients with NSD are under oxidative stress that is relieved following septoplasty.

Serum Oxidative Stress Levels in Patients with Nasal Septal Deviation.

OBJECTIVE: Comparison of the total oxidant status (TOS), total antioxidant status (TAS) and paraoxonase (PON1) serum levels in patients with nasal septum deviation (NSD) and healthy subjects. METHODS: The TAS, TOS, and PON1 serum levels of 47 patients with NSD (mean age 35.3) and 50 healthy subjects (mean age 37.8) were compared in this study. RESULTS: We found significantly higher TAS levels in the control group (p<0.001). The mean TAS value was 1.196 mmoL/L in the control group, whereas it was 1.046 mmoL/L in the NSD group. On the other hand, TOS was significantly higher in the NSD group (p<0.001). We found that the mean TOS value was 6.600 mmoL/L in the control group, and 20.194 mmoL/L in the NSD group. The NSD and control groups had similar PON1 levels (p=0.446). The mean PON1 value was 279.64 U/L in the control group, and 324.21 U/L in the NSD group. CONCLUSION: We detected higher TOS and lower TAS levels in patients with NSD compared to healthy subjects. These results indicate that patients with NSD are exposed to oxidative stress.
